How To Swim Against The Current In Ahnonay

So, you just tried to swim to the tower on that little island, but you missed it, and now the current is dragging you away.
If only you could swim to that nearby low edge, you try again a bit quicker.
Can't be done, right? ... wrong!

It is possible to swim against the current and get back to the low edge.
The first thing you need to notice is the reflected water forming ripples around the edge of the island.
Swim to them and turn so you are against the current.
Follow the island around, keep within the ripples and never stop swimming.
It is slow progress, but if you do this quick enough, it is quicker than letting the current take you.
